  • DETAILED DESCRIPTION OF AN EXEMPLARY EMBODIMENT
  • FIGS. 1-6 illustrate an exemplary beverage preparation machine 1 in accordance with the present invention. The beverage preparation machine 1 includes a housing 2, a lid 3, a handle 4, a base 7, and a receptacle 5 for receiving a beverage cartridge (not shown). The lid 3 rotates about an axis between a closed position (FIGS. 1 and 3) and an open position (FIGS. 2 and 4-6). When moving the lid 3 from the open position to the closed position, the lid 3 rotates toward the base 7. In the closed position, the lid 3 is inclined with respect to the base 7.
  • The receptacle 5 similarly rotates about the same axis as the lid 3. The receptacle 5 rotates between a closed position and an open position. When moving the receptacle 5 from the open position to the closed position, the receptacle 5 similarly rotates about the same axis towards the base 7. In the closed position, the receptacle 5 is parallel to the base 7. In the open position, the receptacle 5 is inclined with respect to the base 7.
  • Penetrating pins are disposed on the base 7 of the brewer. In operation, a cartridge (not shown) is inserted into the receptacle 5 and the receptacle 5 and lid 3 are rotated to the closed position. The rotation of the receptacle 5 and lid 3 to the closed position causes the cartridge to engage the penetrating pins, which penetrate the surface of the cartridge for applying a liquid to the cartridge and retrieving a brewed beverage from the cartridge. When the receptacle 5 of the brewer is moved to an inclined position, or open position, the receptacle 5 lifts the cartridge off of the penetrating pins to facilitate removal of the cartridge from the brewer.
  • When rotating from the open position to the closed position, the lid 3 and the receptacle 5 rotate about the same axis and in the same direction towards the base 7. In the closed position, the lid 3 and the receptacle 5 are parallel to the base 7.
  • When rotating from the closed position to the open position, the lid 3 and the receptacle 5 rotate about the same axis and in the same direction away from the base 7. In the open position, the lid 3 and the receptacle 5 are inclined with respect to the base 7. In the open position, the receptacle 5 faces the inside surface of the lid 3.
  • As clearly illustrated by FIGS. 5-17, the handle 4 includes locking latches 8 that engage locking pins 9 of the base 7 when the lid 3 and the handle 4 are in closed positions. The handle 4 pivots with respect to the lid 3 to rotate the locking latches 8 over the locking pins 9 of the base 7 after the lid 3 has been rotated into a closed position. The locking latches 8 and pins 9 hold the lid 3 and the handle 4 in closed positions in opposition to the force of a lid spring 10.
  • The handle 4 is free to rotate between open and closed positions without causing any rotation of the receptacle 5. Moreover, the handle 4 is free to rotate between open and closed positions without causing any rotation of the lid 3.
  • The lid 3 is also rotatable between the open position and the closed position without rotating the handle 4 from the open position to the closed position. That is, by exerting force directly on top of the lid 3, the lid 3 is rotated from the open position to the closed position while the position of the handle 4 remains entirely unchanged.
  • When the lid 3 is rotated from the open position to the closed position, the inside surface of the lid 3 contacts an upper surface of the receptacle 5 and overcomes a biasing force of a receptacle spring (not shown) which biases the receptacle 5 toward an inclined position away from a horizontal position. Thus, contact between the lid 3 and the receptacle 5 causes the rotation of the receptacle, not the rotation of the handle 4. The rotation of the handle 4 is independent of the rotation of the receptacle 5.
  • Further, the receptacle 5 is also free to rotate between a horizontal position and an inclined position without any rotation of the handle 4 or the lid 3. The receptacle 5 is biased toward the inclined position by a dedicated receptacle spring (not shown). When force is applied to the receptacle 5 the receptacle 5 rotates from the horizontal position to the inclined position without any rotation from the handle 4 or the lid 3.
  • As is clearly illustrated by FIGS. 18-19, the handle 4 is rotatably connected to opposing sides of the lid 3. The handle 4 includes a spring/cam/follower mechanism 11 on each side of the lid 3 adjacent to the locations where the handle 4 is rotatably connected to the lid 3 at pivot 14. The spring/cam/follower mechanism 11 provides a “clicking” feature when the handle 4 rotates from the open position to the closed position. Particularly, each spring/cam/follower mechanism 11 of the lid 3 includes a lid spring 10 (more clearly shown in FIGS. 20 and 21) having a rotatable follower 12 disposed on an end of the spring 10. The adjacent surface of the handle 4 includes a curved or sinusoidal cam surface 13. In operation, the follower 12 starts in a first, original position when the handle 4 is in the open position (FIG. 19). The follower 12 is deflected to a second position by the sinusoidal cam surface 13 of the handle 4 when the handle 4 is in motion from the open position to the closed position, and vice-versa. The follower 12 returns to the first, original position when the handle 4 is in the closed position (FIG. 18). Thus, the user experiences a “clicking” feeling and sound as the handle 4 is moved from the open position to the closed position, and vice versa.
  • The deflection of the follower 12, which results from the movement of the cam surface 13 of the handle 4, is illustrated by FIGS. 18 and 19. When the handle 4 is in the process of rotating from the open position (FIG. 19) to the closed position (FIG. 18), the rotation of the cam surface 13 causes the follower 12 to deflect from a first amount of deflection to a second, higher amount of deflection as the follower 12 crosses the “hump” of the cam surface 13. The follower 12 then returns to its first, original amount of deflection when the handle 4 is in the fully closed position (FIG. 18).
  • The follower 12 of the brewer starts in a first, original amount of deflection (FIG. 19). When the handle 4 is in the process of rotating from the open position (FIG. 19) to the closed position (FIG. 18), the rotation of the cam surface 13 about the pivot 14 causes the follower 12 to deflect from its first, original amount of deflection. The follower 12 then returns to its original, first amount of deflection when the handle 4 rotates into the closed position (FIG. 18). None of the deflection of the follower 12 from the original amount of deflection, which results from the rotation of the handle 4 from the open position to the closed position, remains when the follower 12 is in the closed position, then the follower 12 returns to the original, first amount of deflection.
  • As explained above, the lid 3 is rotatable about an axis with respect to the housing 2. The lid 3 includes a lid spring (not shown) that biases the lid 3 in a direction of rotation toward the open position. The lid spring does not hold the handle 4 in the closed position. The handle 4 can be either in the open or closed position irrespective of the state of the lid spring (deflected or not). Furthermore, the lid spring applies a force to the lid 3 and the handle 4 (as a result of the handle 4 being attached to the lid) toward a lid open position.
  • The receptacle 5 has a dedicated spring mechanism (not shown) for biasing the receptacle 5 toward an inclined position. The handle 4 is free to rotate between an open position and a closed position with respect to the lid, without causing any rotation of the receptacle 5. The rotation of the handle 4 is independent of the movement of the receptacle 5.
  • Further, the receptacle 5 is free to rotate between the horizontal position and the inclined position without any rotation of the handle 4. The receptacle 5 is biased toward the inclined position by the dedicated receptacle spring. When force is applied to the receptacle 5, the receptacle 5 rotates from the inclined position to the horizontal position without any rotation from the handle 4 or lid 3.
  • The receptacle spring does not hold the handle 4 in the closed position. The handle 4 can be either in the open position or the closed position irrespective of the state of the receptacle spring (deflected or not). Further, the receptacle spring biases the receptacle 5 toward the lid 3, and thus, toward the handle 4.
  • The lid 3 rotates about an axis between a closed position and an open position. When moving the lid 3 from the open position to the closed position, the lid 3 rotates toward the base 7. In the closed position, the lid 3 is parallel to the base 7. In the open position, the lid 3 is inclined with respect to the base 7.
